The disclosure includes a watercraft cleaning system that includes a housing, a water input line, a pump and motor system, a high-pressure output line, and a heater. The cleaning system can be arranged and configured to be coupled to a dock post located adjacent a watercraft. The system can easily and conveniently allow watercraft personnel to clean the watercraft.

A pressure washer has a connection for a source of liquid; a high pressure pump; a main line by way of which liquid via the high pressure pump is conveyable from the connection to a spray opening of the main line; and a supplemental pump for adding an additive to the liquid. The pressure washer is conceived in such a way that the additive by way of the supplemental pump is able to be fed to the main line upstream of the high pressure pump.

A mobile high-pressure cleaning apparatus is provided with a vehicle trailer, on the chassis of which at least two running wheels are held so as to be rotatable, and with a high-pressure cleaning appliance having a motor and a pump, and also with at least one water storage tank for storing water for the high-pressure cleaning appliance. So that water can be provided to the apparatus from the at least one water storage tank or from a water supply mains, without risk of water from the water supply mains being returned thereto, the high-pressure cleaning apparatus has a decoupling tank with at least one inlet which can be connected to the water supply mains, and at least one outlet which is connected to the high-pressure cleaning appliance and to at least one water supply tank via a shut-off member which can be actuated by the user.

A quadcopter pressure washer that may facilitate cleaning objects and surfaces in remote areas. The quadcopter pressure washer includes a tubular airframe, a plurality of rotary motors, a battery and controller, a pair of antennae, a signal receiver, a nozzle, a turret, a high-pressure hose, a pressure washer, a direct current or a DC power source, an alternating current/direct current or a AC/DC converter and a 120V AC power source. The quadcopter pressure washer also includes an operator control panel include additional a pair of antennae that extend upward in a programmable position from the operator control panel to transmit or receive any suitable electromagnetic signals. The additional pair of antennae utilizes state-of-the-art Doppler radar technology in electrical communication with the battery and controller. The operator control panel includes a signal emitter positioned in front of the operator control panel.

An example automatic kitchen cleaning system includes a control box configured to, in response to receipt of the start signal to initiate the first cleaning operation of the cooking range exhaust system, causing the first detergent and water to be mixed in a reservoir at the first target mixing ratio for form the first cleaning solution. The control box is further configured to, in response to receipt of the start signal to initiate the second cleaning operation of the waste conduit, causing the second detergent and water to be mixed in the reservoir at the second target mixing ratio to form the second cleaning solution.

The disclosure provides a resin cleaning device and method. The resin cleaning device includes a control system, a treatment unit, a driving unit, and a feedback assembly. The treatment unit, the driving unit, and the feedback assembly are respectively in communication connection with the control system. The treatment unit is configured for treating a member-to-be-cleaned so as to reduce a viscosity of resin on the member-to-be-cleaned. The driving unit is configured for driving the member-to-be-cleaned to rotate. The feedback assembly is configured for acquiring a position signal of the member-to-be-cleaned and feeding the position signal back to the control system, such that the control system controls the treatment unit and the driving unit according to the position signal. Through the above manner, a more intelligent resin cleaning process with a better cleaning effect may be realized.

A heavy duty washing apparatus for cleaning cooking substrates including hotplates and grills comprising: a. a self-contained housing allowing readily movability; b. a plurality of functionally interconnected stations for receiving supply of water, a chemical cleaning agent composition and a pressurised fluid; c. a pressurising station and a temperature conditioning station; d. a foam generator in the housing using controlling feeds from the plurality of interconnected stations and functionally engaging with the pressurising station and the temperature conditioning station for providing an effective chemical cleaning agent composition for conditioning one or more of the supply of water, the chemical cleaning agent composition and the pressurised fluid and e. a washing compartment adapted to receive one or more of the cooking substrates in a stackable substantially planar spaced array; wherein the effective chemical cleaning agent composition allows for cleaning over an effective cleaning time in a chemical, aerobic and physical manner cooking residues on the cooking substrates by retaining of said foam layer for a predetermined period in contact with the cooking surfaces, and rinsing the foam layer with preselected conditioned high temperature and/or pressurised water to remove chemical and food residues.

A cleaning system includes: a pump portion that includes an air chamber that is capable of drawing in air from an outside, and an oscillating body which oscillates due to vibration of a vehicle and changes a volume of the air chamber so as to discharge the air drawn in the air chamber from the air chamber; and a nozzle that is disposed to face an information collecting surface of an information acquiring portion provided in the vehicle and injects the air discharged from the air chamber onto the information collecting surface.

An all-electric pressure washer heater module having a heating coil and a heating element is disclosed. A system for all-electric pressure washing is further disclosure. In particular, the all-electric pressure washer heater module contains the heating element from exposure to corrosion and fouling.

Disclosed herein are methods for improving safety and delivery of commercial application of cleaning compositions that include enzymes and other protein irritants. The methods reduce the mist and aerosolization of proteins so that inhalation and exposure to the same are reduced. According to the invention, when commercial pressurized sprayers are used to apply protein containing use cleaning compositions of up to 5 ppm protein, aerosolization is decreased to below 60 ng active protein per meter cubed. Applicants have also identified a specific metering tip/nozzle, dispense rate, and low pressure application of not more than 100 psi are critical to achieving the benefits of the invention.
